The Samsung Galaxy Watch4 Classic, and indeed the entire current Galaxy Watch4 line, is the most advanced and functional smartwatch for Android smartphones and, in particular, Samsung at the moment. They use a new hardware and software platform. Thanks to the use of Wear OS, integration with Android smartphones has become more dense and convenient. There are a decent number of fitness apps available, and more: Spotify, YouTube Music, Google Keep, and maps will not be superfluous either. And finally, there is support for Google Pay, which has been waiting for so long in Samsung smart watches. In terms of health and fitness functions, there is everything and a little more: the ability to determine body composition has been added to all the usual functions. The watch still looks great, the controls are comfortable, and dust and moisture protection allows you to wear it while swimming, provided that the dive is shallow. The only significant complaint about the Samsung Galaxy Watch4 Classic is a modest battery life: with the full use of all functions, you will have to charge every day.
